ERINTING AN D FOLDING MACHINE.

Application filed Getober 17, 1913, Serial No. 796,080. Renewed November 17, 1919. ,Srial No. 3385M. I

T all whom it may concern Be it known that 1, JOHN A; Boron, a citizen of the United States, residing at Chicage, in the county of Cook and State of Illinois, have invented new and useful Im- A I Printing and FoldingMachines, of which the following is a specification.

My invention relatesto improvements in machines for printing and folding papers and relates more particularly to that class rotary webprinting, folding, and delivering machines.

A primary object of my invention is to reduce the number of stereotype plates employed, by providing a single set of plates on each printing cylinder, whereon have formerly been used duplicate plates, and, in lieu of a second set of plates, to provide a second impression roller, whereby to accomplish the novel and effective result of perfecting the web by negotiating two like impressions thereon, one followingthe other with usual margins intervening, in each complete revolution of the plate cylinder, resulting in the increased efficiency of the machine.

Another object is to provide means for relieving the pressure between the plate and impression cylinders when the press is standing idle, without the necessity of removing the stereotype plates.

A further object is to provide an effective forwarding devicecontrolling the web and relieving the strain thereon, which device will make it possible to thread the web into the printing and folding machine without the necessity of having any of the plates in place on the cylinders.

It is a well known fact that form rollers,

covered with composition, are very expensive and are easily worn out. In order to render my printing machine more economical and efficient, I provide means whereby these rollers may run on a smooth surface for one-half of each revolution of the plate cylinders, thus effectively reducing the wear on the rollers.

A still further result which I desire to attain in my invention is to make it possible to use but a single ink fountain foreach plate cylinder by the adoption of a novel and effective method of ink distribution.

lVith the above and'other objects in view, my invention consists of the novel construction and arrangement of the. several ele- Specification of Letters Patent.

ments of my printing and folding machine, which features will be hereinafter fully described, illustrated in the accompanying drawings, and pointed out by and in the appended claims.

Reference may be had to prior patents granted to me bearing the following designation, #963,203, patented July 5, 1910 and 924,310 patented June 8, 1909, wherein several of the features embodied in my present invention are partially disclosed, but in my present disclosure substantial improvements thereon will be pointed out and illustrated in the drawings.

In the drawings; wherein like reference characters refer to like or corresponding parts throughout the several views, it has been deemed expedient to employ conventional and diagrammatical means of illustration where possible, since the elements, when not otherwise shown in detail, are to be understood to be of the usual, or any approvedconstruction, well known in the art.

In describing the printing press of my inventidn it is not thought necessary to go into detail regarding that portion of the apparatus which is known to be old and which ll do not attempt to cover by Letters Patent. I therefore limit the detail description, in so far as possible, to the portion of the device which ll claim as new. l have also illustrated a threedeckmachine, but wherein the three decks are similar, I propose to describe but one deck, it being understood that the other decks are similar in arrangement and operation.

The supporting frame work is designated in general by the reference letter A, and which follows the usual accepted design. The several cylinder members are mounted pro ided therefor in the usual manner. I have, however, provided a novel arrangement of the several elements of my machine with refrence to the central vertical frame columns A by positioning the plate cylinders 7 and 10 at a suflicient (llStZtllC-B from the column A to allow easy access thereto pplying and removing plates. By mounting Amy relatively small impression cylinders "6 and 15 on a line with and between the plate cylinders, I ham also economi' -:d the space and rendered y plate cylinders more accessible. By proi the vertical drive shaft 24-, (see Fig. on one side of the machine, and the driving on the opposite side, I am enabled to have the shaft side of my pres relatively free from mechanism to ob struct the access to the plate and other cylinders.

By reference to. that l have provided the normal operation. with only i, it will, be seen plate cylinders for a hall a con -web bet-ween the Web provided with a bevel formed on the plate cylinder, but'it is prel erable to provide a removable plate, as will hereinafter appear. The plate cylinders 7 and 10 are in circumference equal to the lengthmf two plates plus margins, the col.- umns of the stereotype plate running circumferential thereof. It will be understood that the stereotype plate on one cylinder is adapted to perfect one side. of the web, while the other side of the web is perfected by the other plate cylinder.

By reference to Fig. l, it will be seen that the web is introduced to the press in a novel manner. It was prior practice to introduce the web from a roll of paper such as l to pass between the impression cylinder and the plate cylinder. I employ a web forwarding device consisting of a. set of web directing rollers 2, 3

and let, to a roller 5 and thence downward between the impression cylinder (5 and the plate cylinder 7. At. this point the web is perfected by the plate cylinder 7 and passes under rollers 8 and 8' and upward between plate cylinder 7 and the second impression cylinder 9. The travel of the web is so predetermined that the second impression given to the web by its second contact with the stereotype plate 11 Fig. 11) will be properly spaced thereon, that is to say, the two impressions will be positioned one after the other on the web, double margins intervening. The web is then turned and di rectod by rollers 17 and 18 to pass over impression cylinder 15 and downward between that in'ipression cylinder and the plate cylinder l0, and under rollers 19 and 20 to pass upward between the impression cylinder 16 and plate cylinder 10, where the web is perfected on the opposite side.

I have provided a novel means for driving the several rotating parts of my invcntion, "which consists of shown in Figs. 2 and 5.

natcs a horizontalshaft which extends crosswise of the machine, and is positioned preferably bei'icath the machine. Shaft 21 is gear 22 which is positioned. ust outside of and below one of the side walls of the frame and which is adapted to mesh with a second bevel gear :23 carried by a perpendicular shaft 24. Shaft 24 is provided with other spaced apart bevel gears designated as and which may he termed deck-driving gears. Gears are adapted to sh with gears 26, which the arrangement gears are mounted'on the shaft 38 of the forwarding roller 13. Shaft 38 is proa ided at ts opposite end, and on the op posltc side and 4 which direct theforwarding rollers 13' Numeral 21 desigcylinder gears designated as 81 and composition form rollers 61.

the machine, with spur gear 40 adapted to mesh with spur gears 27 and 28 suitably located or, either side thereof on the same side of the machine. Spur gear 27 is mounted on shaft 39, upon which shaft is mounted the second web forwarding roller 14. Spur gear is adapted to mesh with a spur gear 26 carried on shaft'30, upon which shaft 2 l) is also mounted the plate cylinder 7. Meshing with gear line with shaft are the two impression 32 mounted respectively on shafts 41 and.42. The other plate cylinder gear 29 mounted on shaft 30, is driven from spur gear 27 through the medium of spur gear 35. Impression cylinder gears 32' and 31' aredriven by the plate cylinder gear 29'.

Fig. 22 illustrates my method of throw ing any one of the decks out of operation.

Gear is slidably keyed to shaft 38 upon which is mountedforwarding cylinder 13'.

By sliding gear 40 outward on shaft 38, the entire deck will be thrown out of operation.

In my present invention. wherein is pro vided for normal operation only half a complement. of plates, I provide but a single ink fountainto each plate cylinder. I employ in conjunction with the ink fountain 50, ink roller 52, ductor roller 53, ink drum 54, vibrating rollers 57, 58 and 59, and iron ride-r 60, through the medium of which the ink is 7 carried from the fountain and placed on the Rollers 61, of which there, are. two, (see Fig. 11), are mountedupon supporting arms 78, which arms are carried by brackets 79 attached to the frame. Rollers 61 are adapted to ink plates carried by the plate cylinder. A second pair of-form rollers designated as 62 are supported by a second set of arms 78 and are positioned below the plate cylinder 4 being adapted to travel upon the plates carried by the plate cylinderl Means which will be hereinafter set forth are adapted to raise and lower the'form roller members 61 and 62 to accommodate the two previously mentioned heights of plates applied to the plate cylinder. It will be readily seen that the ink placed on the smooth plate 12 car ried on half of the surface of the plate cylinder by the rollers 61 will be taken up by the second set of rollers 62 and placed upon the stereotype plate during the following half revolution of the cylinder.

I employ the ordinary type of ink roller 52 having a cam on one end thereof by which the ductor roller 53 is actuated into contact with the ink drum 54, but I provide a new and eificient'method of adjustment therefor, which is adapted towork inconjunction therewith." (See Figs. 65nd 7.) A cam designated as 80 is attached to the ink roller shaft 51 at the opposite end from cam whereby the roller may 29 and preferably located in .ard.

.removed and the impression roller 9, In addition to the usual supporting arms 77 of the ductor roller 53, I. provide an adjustment arm 76 which is fixed to shaft to which arms 77 are attached. A roller 81 is carried by arm 76, which roller is adapted to run on cam 80. By any suit able method, roller 81 may be movably attached to the outer end of arm 76, as by being adjustably carried in a slot therein,

be shifted into actuated relation with cam 80. Cam is positioned to actuate roller 81, and, thereby, arm '7 6 and ink ductor roller 53, away from the ink roller 52-, at the point in the revolution ofth'e ink roller just before the cam 79 is in posit-ion to likewise actuate the ductor roller. By this means, the length of time in. which the ductor 53 is in contact-with ink roller 52 will be diminished, and, consequently the amount of ink taken up by the ductor roller 53 will be correspondingly decreased.

By reference toFigs. 9 and 10, the method of providing adjustment for the impression v a nut and lock nut 69 are carried by said adj usting bolt on the opposite side of the stand- A nut 7 O is carried on bolt 66 between head 83 and standard 82, and a bifurcated key 65 straddles the adjusting bolt 66 between the nut 70 and the standard 82. When quick adjustment is required, key 65 may be hearing shifted in position. To provide movement of bearing 64 in the opposite direction, I provide a wedge 67 having a tapered face adapted to slide on a similarly tapered face carried by hearing block 64, and an adjusting screw 68. By forcing wedge 67 downward between the tapered face of block 64 and the wall of opening 63 by'means of the adjusting screw 68, movement "of the block may be readily accomplished.

The arrangement of the several elementsv of my machine makes it expedient to employ such means as are illustrated in Fig. 10 for the adjustment of the bearing for impression roller 6. A rectangular opening 74 provides a slide way'for bearing block 71, in which shaft 42 rotates. Both of the end faces of block 71 are tapered, and similarly tapered wedges 72 are provided, which wedges are adapted to be actuated upward and downward between the walls of opening 74 and the tapered faces of block 71, by set screws 78, thereby providing adjustment of position for the impression roller.

Improved means for driving the ink rollers is clearly illustrated in Fig. 8, by reference to which it will be seen that bevel carried by shaft 30 of the plate cylinder, drives a relatively larger bevel gear keyed to the ink roller drive shaft 85. Shaft extends at right angles to shaft 30 and carries a bevel gear 86 on its opposite end, which bevel gear drives a second relatively larger gear 87 mounted on the ink roller shaft 51, resulting in a continuous revolution at a r duced speed of the ink roller 52 in fountain 50. l

The means employed for vibrating the several ink distributing rollers 59, 58. and 57 is well known to the are, and is accomplished eccentrics 88 carrir on shaft 85, but 1 have embodied novel 1 rovementstherein. Previously a vibrating .1 such as 190 has been employed for each r to be vibrated, and the eccentrics 88 were axed to their shaft to actuate the rollers at different points in the revolution of their drive shaft. This drive was accomplished by special gearing on the opposite side of the printing machine and was complicated and difficult of access. I propose to actuate my rollers 57, and 59 at the same time by arranging eccentrics 88 on the ink roller drive shaft 853 to so operate,

and to provide an extension arm 197, at-' tachcd to arm 1%, to vibrate roller 58;

The means which I employ for raising and lowering the form rollers 61 and (52 is shown in perspective in Fig. 11. The supporting arms are shown in greater detail in Figs. 12 and 13.v Arms 78 are anchored by means of brackets 79 to the frame, and positioned so that the shafts of the form rollers 01 and 62 may be carried in the bearing slots 90 provided in bearing brackets 93, key 91 being adapted to secure the shafts in place. Bearing brackets 93 are slidable upon their respective arms 78, and are held in place by nuts 94 on either side of the l..-Sl1aped projection 96 through which adjusting stud ex tends. Adjusting stud is formed integral with arm 78 and is a continuation thereof. The opposite end of arm 78 is bifurcated. and a roller 97 is pivoted between the bifurczu tions. intermediate the lugs ilti of bracket 79, a coil spring 99 is carried by arm 1'8. Spring 99 is seated at its outer end against one of the lugs 98, and at the other end against pin 100 carried by arm 78. Rollers 97 on the inner ends of arm 78 are adapted to roll upon the revolving shaft 30 of the plate cylinder 7. In order to raise the form i'ollers carried by arms 78 to accommodate thetwo heights of plate carried by cylinder 7, I provide a raised surface 106 on shaft 30 in the path of travel of the rollers. The raised surface 106 corresponds in height to the difference in height the stereotype plate 11 and. the smooth surface plate 12 on cylinder 7, and is prcmerly positioned. raise the rollers when, they are to tnrrel on thc stereotightly in place. Cog 116, and coacting deg 11.7 prevent reverse motion of the rod 11%. e

the cylinder in which it may he rotate type or thicker plate 11. An adjusting cc centric 101 is pivoted by screw 102 to arm 7b and by rotating eccentric 101 by means key 103, the shiftihg of position of bearing brackets 93 may be effected, the eccentric be ing adapted to contact With stationary bracket 79 in which arm 78 is slidable. Notchcs 105 are adapted to receive pin 10% at the several predetermined positions of adjustment. Adjusting eccentric 101 makes it possible to raise the rollers 97 entirely out of contact when the machine is at rest, or, when it is desired to use a full complement of stereo type plates when increasing the capacity of the machine, the rollers may be adjusted to operate in the position where they will just touch the plates.

l igs. 14- and 15 illustrate my improved method of attaching the blanket and muslin to the impression cylinders 1 provide a longitudinally extending slot 106 through the outer walls of the impression cylinder, one edge of aid slo't being provided with series of pins 107 extending therefrom.' The blanket and muslin covering therefor are caught in the pins 107 and drawn around cylinder and threaded into the slot 106, which slot is preferably only wide enough. to receive the blanket and muslin cover. The free end of the blanket is then threaded into the longitudinal slot 108 carried by roller 109 and the roller revolved about axis in the impression cylinder heads, and the blanket thus rolled thereon and d awn tight about the impression cylinder. :ewise the free end of the muslin is threaded into slot 110 of the roller 11]. and drawn tightly in place. Dogs 112 coact with cog wheels 113 to prevent the unrolling of the rollers 109 and .111.

Means for tightening the packing al the forwarding roller 13 is shown in 17, 18 and 19. Cylinder 13 provided. a relatively narrow limgitiulinal slut communicating with :1 preferably rectau lar longitudinal opening 113 carr cylinder. A square sectioned 11-1 tends long tudinally of the opening 113 is provided with a bearing in the heads o The packing material for the f fashioned to form a substantially'e cover, and the seam 1E; caught in carried by rod 11%, whereby the packii'ig may be wound about-rod 114 and drawn For the tightening. of the packing about forwarding roller 14, 1 provide. the means shown. in Figs. 9,0 and 21. Two relatively wide slots-11b are formed longitudinally of cylinder 1 preferably degrees apart and each extend from opposite ends to points adjacent thecenter of the length of the cylinder, A square rod 1.19 is carried 118 and the other free end carried around the cylinder, threaded into slot 118 and caught by pins 121 carried by rods 119. The rods may then be rotated to tighten the packing about the cylinder. Means similar to that shown in Fig. 19 may be employed to prevent reversed motion of rods 119.

A paper tensioning device such as is shown in Figs. 3 and/1 are employed, numeral 123 designating a bearing drum adapted to receive shaft 122 of.the paper rolls 1. Clamps 124 and 125, adapted to be adjusted by hand screw 126, provide tension about the bearing drum 123 into which shaft 122 is keyed. Longitudinal movement of the paper rolls is secured by means of feed screw 127, by which block 128 may be actuated in and out, and with it the drum 123, and paper roll 1, block 128 fitting into a groove 129 therefor in druni 123.

I have provided the means shown in Fig. 23 for flexibly mounting the ends of roller 2 whereby the web in passing from the paper rolls 1 may be held tight and yet allow roller 2 to shift slightly at either end upon the event of unevenness in the paper roll. Numeral 190 designates a bracket, mounted to the main frame A in any suitable manner, and having slidably mounted therein, a pin 191. Pin 191 is preferably placed to slide back and forth in line with the pull on the web, and coil springs 192 and 193 are carried about said pin on either side of the bracket 190. On; one end of pin 190 is mounted the bearing fixture 194 in which the shaft of roller 2 is mounted to rotate. A fixed collar or head 195 is carried by the opposite end of pin 191, and forms a seat for the spring 193. t will be seen that such an arrangement provides flexibility in both directions and will readily compensate for any unevenness gear 135 which is in the pull on the web, thus preventing the breaking of the web caused by such uneven ness.

After the several webs have passed through the process of being perfected on both sides, they are collected by being directed about rollers 170 to pass over roller 136 leading to the folding device which is illustrated in Fig. 24. The shaft on which roller 136 is mounted is rotated by a bevel actuated by a bevel gear Y vertical shaft 124. Shaft 124 is driven by shaft 127 through the medium of bevel gear 126 on shaft 127 and bevel gear 125 on shaft 124. Shaft 127 is actuated from the main drive shaft 21 through the medium of bevel gears 1.33, 132, shaft 131 and bevel gears 129 and 128. This 134 mounted on drive may be readily understood by refer-'- ence to Fig. 2. Parallel to and aboveroller 136 is a shaft 137 provided with fingers 138 on the end of which fingers are mounted rollers 139 for the purpose of providing tension at this point inthe. run. Numeral 140 designates a former which is of the ordinary type and which folds the webs lengthwise between the pages. The perfected webs pass downward therefrom between rollers 142'and 141, which rollers are geared to revolve in opposite directions and thus to forward the folded webs downward between the folding cylinders 143 and 144. Cylinder 144 is'provided with a knife 17 3 which is adapted to engage in slots 172 carried by cylinder 143 each der 144 and each half revolution of cylinder 143. This arrangement is shown in detail in Fig. 29.

I provide my folding cylinder, as shown in Figs. 25, 26 and 29, with the usual set of forwarding pins 163 which'are adapted to protrude from the cylinder through slots 164. Pins 163 are mounted on arms 162,

- which arms are carried by shafts 161. mounted longitudinally of the cylinder at substantially 180- degrees apart and which shafts are actuated by means of arms 160 outside of the cylinder, which arms are provided with rollcrs 167 adapted to ride on a stationary cam 159 provided also without the cylinder. Cam 159 is carried by a stationary drum member 157 of which there are two, the other being designated as 157 and positioned at the opposite end of cylinder 143. Drum members 157 and 157 provide channels 158 and 158 in which spur pinions 156 mounted on the ends of the shafts carrying the folding blades 165 may travel. Folding blades 165 are also mounted within the folding cylinder 143, longitudinally thereof, and are adapted to revolve in slots 168 provided therefor. At predetermined points in the channel 158 are teeth adapted to mesh with the spurs 156 to revolve the folding blade.

- It will be seen that as the folded web passes between the cylinders 143 and 144 pins 163 will engage the edge of the web and carry it downward with the revolution of folding cylinders 143 one-half of the distance around the folding cylinder. At this point, pins 163 of arm 160 and its roller 167 upon cam 159.

At this point, also, the folding blade 165 will have reached a position just above and between rollers 151 and 152, when it will be revolved in slot 168, through the actuation thereof by spur pinions 156, and one of the sharp edges thereof turned downward between rollers 151 and 152. Knife 1730f cylinder 144 will have reached its positlon to register with slot 172 of cylinder 143,

and the-paper will be severed from the web.

full revolution of cylindownward between Revolving rollers 151 and 152, revolving in Opposite directions, will draw the paper them depositing the folded paper, upon the deliveringdevice 150, which, in turn, will deliver the paper to the moving tapes actuated by rollers 155 and 154 in a well known manner.

The foregoing folding device is clearly pointed out in my prior Patents and 900,259 and, since reference may be had thereto, it is not thought necessary to describe the previous disclosure in detail.

Folding cylinder 1 13 is driven through thclnedium of the chain of spur gears 148, 149, 175 and 130 from shaft 131. p 151 and 152 may be driven by gear 148. The delivering, device shaft 150 and the rollers 155 and .154 may be driven by any suitable manner which is not new and which is well known in the art.

It will be found advantageous, in increasing thecapacity of my printing machine,

- to print. with a full complement of plates on each of the plate cylinders 7 and 10. Fig. 27 illustrates a run in. which the cylinders are thus provided with two of stereotype plates, the columns extending circumterentially of the cylinder. T he web is passed between the forwarding cylinders 13 and 14 downward around roller 5 and over and between impression cylinder (5 and plate cylinder 7. The web is tllGIlPllSSQCl downward around roller 8 and upward passing down between impression cylinder 15 and plate cylinder 10, thence under roll- Roller? withdrawn from contact with the web. The web is passed under roller 5 thence over impression cylinder 15 and between that impression cylinder and plate cylinder 10, upward from the impression cylinder 15 and downward between impression cylinder 6 and plate cylinder 7, under rollers 8 and 8', and upward between impression cylinder 9 and plate cylinder 7, then downward from impression cylinder 9 passing under rollers 17, 18 and 20 and upward between impression cylinder 16 and plate cylinder 10. It will be understood that in this run the plate cylinders are provided with but a half a complement of plates, that is one stereotype plate and one smooth plate oi less thickness, and that all of the impression cylinders and form rollers are in operation. In this run it is possible to provide tension to the web at all times, as the web will be in contact at some point during entire run.

in order to accomplish the foregoing re sult, it is necessary to provide the adjustment for web directing roller 20 which is shown in Fig. 16. Roller 20 is mounted upon arms 185 which arms are pivoted at point 186 to a pivoting plate 187 which.

may be mounted upon the frame of theers 19, 20, and 170 to the folding device.

When this run is used the lower set of form rollers 62 and 62 are thrown out of commission, by shifting the position of those rollers by the actuation of cam 101 carried by hanger arm 78 to the dotted line position shown in Fig. 13.- Impression cylinders 9 and 16 are also. thrown out of commission by ilneans of the adjusting device shown in In accomplishing the foregoing, it will be necessary to collect below the former. The method therefore is clearly disclosed in my former Patent #974,231 granted Nov. 1, 1910, and reference may be had thereto, or any other approved construction may be employed.

I have provided a means for omitting the forwarding cylinders .13 and 14 out of the run of web when it is so desired,. by means of the run shown in Fig. 28. Forwarding cylinder 13, which may be sup ported by bearings 200 carried on brackets 201 supported on each side of the machine by central columns A, is laterally adjustable with respect to the other forwarding roller 14. Bearing 200 is slidable on bracket 201, a' screw adjustment 203 being provided to accomplish the movement thereof. Through this means cylinder 13 may be an adjusting bolt 189 may extend.
